SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 234,743, dated November 23, 1880.

Application filed September 4, 1880.

To all whom it may concern:

Be it known that I, AxEL FERDINAND BERGQVIST, of Fairfield, in the county of J efferson and State of Iowa, have invented a new and Improved Sulky-Plow; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation with the near wheel removed. Fig. 2 is a vertical section through the line x acof Fig. 3. Fig.3 is a rear elevation. Fig. 4 is a plan view.

My invention relates to certain improvements in sulky-plows; and it consists in the peculiar construction and arrangement of parts for raising and lowering the bail to which the plow is attached and simultaneously adjusting the wheel which runs upon the landside.

It also consists in the peculiar means for connecting the plow-beam to the bail, and also, further, in the peculiar construction of the frame or carriage, as hereinafter more fully described.

In the drawings, A represents the main axle, which is cranked or bent down at one end and provided with a journal for the wheel 1-3, (see Fig. 3,) and at the other end is bent down and perforated with a hole, which forms a bearing for a short rock-shaft, O, which carries the landside-wheel B. attached the U-shaped metal frame D, Fig. 4., which is composed of flat iron bent over the axle and fastened to the same by clip a, the ends of which irons are bent down in rear of the axle and provided with bearings b for the plow-bail E, and which ends are also stiffened or braced by bracket-pieces c, Fig. 2, which extend from near the middle of the side barsof the U-shaped frame down beneath the axle, and then to the lower bent end of said frame, where it is riveted or bolted, and terminates in an eye, (I.

For simultaneously operating the bail and the landside-wheel, I locate upon the main frame D a hand-lever, F, having its fulcrum at c, and provided also with a lockin g device adapted to co-operate with a notched bar, G, to hold the lever in its several adjustments.

To this axle is' (No model.)

The lower end of this lever, below its fulcrum, I connect, through two link-bars, f, with a cranked extension, g, from the bail, while above its fulcrum I attach a long link, h, passing over the top of the axle and jointed at its rear end to a crank, i, rigidly fixed to the short rock-shaft O in rear of the axle. This rock-shaft is carried in the perforated bearing of the crank-axle at one end, and at the other end (next to crank is carried in a bearing in a pendent arm,j, bolted to the axle. Outside of the main axle this rock-shaft is provided with a disk, It, to which is fixed a crank, l, carrying thejournal for the landside-wheel.

Now, when the hand-lever F is drawn back it will be seen that a downward pull is exerted upon the crank g of the bail and the plow is lifted out of the ground. At the same time, also, a downward push is exerted upon the crank t, which throws the landside-wheel down also to the level of the other wheel. When the lever is, on the other hand, thrown forward a pull is exerted upon the crank 1', raising the wheel B the depth of the furrow, so as to run on the landside, and the bail is simultaneously let down to allow the plow to enter the ground.

By altering the relation of the crank l, or putting it in front of the axle, the device may be adapted to a right or left plow, as may be desired.

I or connecting the plow-beam H with the supporting-bail a clip-plate, m, is fastened to the beam and a swinging plate, a, is loosely supported at its middle upon the bail, and is connected to the clip-plate below by a bolt, so as to form a flexible joint. The platen has free lateral movement along the whole extent of the cranked portion of the bail, and its upper end is connected to the forward end of the clip-plate by a chain, 0, Fig. 1, which prevents the plow from being pulled out of the ground by being drawn forward under the bail by its draft-connection. Thcsedraft-connections consist of a ring at the forward end of the beam and two chains, also connected to the forward end of the beam, and extending back to and hooking over the eyes d.

Kis the tongue of thesulky-plow, which consists of a single straight wooden beam, which is bolted to the cross-bar of the U -shaped frame, and also to the axle. L is the drivers seat, fixed upon the axle.

I am aware that itis not broadly new to connect the hand-lever of a sulky-plow with the bail and adj ustable wheel, so as to raise the plow and lower the Wheel by the same movement, and I do not claim this, but only my construction of parts for accomplishing such result.

Having thus described my invention, what I claim as new is- 1 1. The combination, with the bail having a crank-extension, g, and the wheel B, carried by a rock-shaft, (J, having cranks i and l, of a lever, F, connected above its fulcrum with the crank i by a link, h, passing over the axle, and connected below its fulcrum and below the axle with the crank of the bail by link-bar f, substantially as shown and described.

2. The combination, with the bail and the plow-beam, of the clip-plate m, fastened to the beam, and the swinging plate n, connected at its middle to the bail and jointed to the clipplate, and a chain, 0, connecting the upper end of platen with the forward end of the clipplate, substantially as shown and described.

3. The combination, with the axle and the bail, of the U-shaped frame D, bent over and extended down below the axle in the rear thereof. and provided with bearings for the bail, and the braces 0, passing beneath the axle and connecting the side bars of the frame D with its rear and pendent ends, as shown and described.
